welcomed the idea of the Big Society but claimed that Cameron was "undermining" it. His concerns were about cuts in government money going to charities coming "too far and too fast". He later said the project had become a "wreck". Steven Kettell of the University of Warwick has written of the intrinsic "problems surrounding the government's call to put religious groups at the centre of the Big Society agenda". In April 2012 criticisms were raised concerning the shortage of Big Society policies across Government, such as the lack of employee-owned mutuals and social enterprises in public sector reforms as well as the introduction of a cap on tax relief for charitable giving in the 2012 Budget. A report published in May 2012 suggested that the £3.3 billion cuts in government funding to the voluntary sector between 2012 and 2015 had greatly reduced the capacity of voluntary groups to implement Big Society projects. Bernard Collier expressed concern that the policy's lack of localism was "favouring big charities" and ignoring the "potential contribution of local voluntary and community organisations". In 2014 former Cameron aide Danny Kruger said that although the relevant legislation had been put in place, the policy had been downgraded from its original role due to a lack of leadership. At the same time a Centre for Social Justice report suggested that the policy was having least effect in the poorest in the country where it would be most useful. Cameron responded that the public sector had already failed to prevent the poorest parts of the country becoming so, and that there were examples of the Big Society having been effective in poor areas. Decline During the course of the 2010–15 government the Big Society declined as an instrument of government policy. Cameron did not use the term in public after 2013 and the phrase ceased to be used in government statements. The collapse of the Big Society Network in 2014 and criticism of the Prime Minister's relationship with it were followed by a critical final Big Society Audit published by Civil Exchange in January 2015. The audit highlighted cuts in charity grants and restrictions on the right to challenge government policy through the courts as undermining Big Society ideals. It noted that charities have had a decreasing role as government contractors due to policies which favoured the private sector and it pointed out that the centralisation of the British
